Electronics Task 1

Differential Transresistance Amplifier. Vout = (Iinniv - Ininv)(Rm) Vout = (Iinniv - Ininv)(Rg) For this particular circuit with the saved values Rnivg = Rg = Rf Vout = (Iinniv - Ininv)(200 kΩ) Examples: 1. For the saved values; Iinniv = 75 µA, Ininv = 50 µA Vout = (75 µA - 50 µA)(200 kΩ) Vout = (25 µA)(200 kΩ) Vout = 5 V 2. Iinniv = 25 µA, Ininv = 50 µA Vout = (25 µA - 50 µA)(200 kΩ) Vout = (-25 µA)(200 kΩ) Vout = -5 V 3. Iinniv = 75 µA, Ininv = 60 µA Vout = (75 µA - 60 µA)(200 kΩ) Vout = (15 µA)(200 kΩ) Vout = 3 V
